Weld-In Thermowells
 |
To protect thermometers and temperature probes in steam lines and other high-temperature and high-pressure applications, these thermowells weld into place for a more secure connection than threaded thermowells.
316 Stainless Steel—316 stainless steel thermowells are extremely resistant to corrosive chemicals.

Noncontact Temperature Sensors for Tanks
 |
Take your tank’s internal temperature with these sensors that sit on the outside walls. Since they don’t touch your tank’s contents, they won’t cause contamination or corrode. To attach the sensor to your tank, weld the included studs to your tank's walls, or stick them on your tank using adhesive. Either way you mount them, you don’t need to drill or drain your tank, saving you from scheduled downtime.
They have internal sensors to record the tank’s thermal conductivity, which is used to calculate your tank's internal temperature.
4 mA to 20 mA Output Signal—The information is sent through a 4-20 mA signal, so you can read the temperature on controllers and data loggers.
For 1/8" Tank Wall Thickness—These sensors are preconfigured for stainless steel tanks with ⅛"-thick walls.

Use adapters to calibrate these sensors on your computer when your tank isn’t the default thickness or material. Download free software and material presets to help you calibrate the sensor. If you know your tank’s thermal conductivity, you can add another material. The software also lets you monitor and log temperature.
